Why did we abandon hydrogen cars so quickly?

[x4it3n]

Hydrogen is too expensive and still dangerous. Cold fusion is the best technology we have as of now, it's a clean energy but the lobbyists are pushing for gas because the gas industry brings too much money. The reality is that our society is doomed because of selfish and greedy people...

Hydrogen is too expensive and still dangerous.

And 95% of it comes from fossil fuel, and overall efficiency of using that fossil fuel is less than using it directly in a gasoline engine, so it is completely pointless.

Cold fusion

But... how cold? Yes I remember the fraud from pons and fleischmann. Do you remember that?

Isn't electricity powering BEV also made from fossil fuel power stations? What's the difference between making hydrogen with grid electricity and powering a car with it ?

Also worth noting there's nothing stopping hydrogen being produced using off peak green energy, especially for things like wind. Given there's no way to store it as of now. Plus natural hydrogen exploration is only just getting started.

BEVs sales are in big trouble and outright cratering in the Europe. Amazing to me people are pushing this technology when consumers just aren't interested much and for good reason. (Similar for a lot of other tech now as well like Consumer LLMs)

Similar concerns, sure, but at least the efficiency difference is positive and the infrastructure isn't so absent.

Hydrogen is the same problem, except you use more fossil fuel instead of less fossil fuel and you don't have many options to 'recharge'. There is no existing hydrogen grid to utilize. Building the missing infrastructure requires more carbon demand. You don't build a hydrogen infrastructure in order to create a less efficient way to consume fossil fuel, unless your goals are money in opposition of the stated goals.

There is no natural hydrogen to gather and collect. It is too reactive.

The only way to efficiently use off-peak green hydrogen is to use it as off-peak storage tied to the grid directly. Make hydrogen fuel cells which consume electricity when the grid is in excess and consume hydrogen when the grid needs power. Do that with all the excess green power first. Then, when you have nothing better to do, waste your time with hydrogen cars. Make it stationary, efficient, and effective first. Similar reason as to why solar panels are on houses, not on cars. You do the thing that's most efficient and makes sense first. Then waste your time on investor-funded toys afterward. You don't do the less efficient thing first, especially when it is less harmful to do nothing at all.

This is nothing that it cold in process of fusion. The coils of the electromagnets and the walls of the reactor are cooled. This is no reason to call it "cold fusion".

My bad I checked and it's actually Nuclear Fission and Fusion that Bill Gates is investing on

Sounds like converting from gasoline to hydrogen means 30% of the range for equal power, roughly:

700 psi just isn't dense enough.

And it is completely irrelevant (or worse) to the goal of ditching fossil fuels.

 

[FordGT90Concept]

Green and purple/pink are environmentally friendly and should contribute to lessening demand for carbon. Blue and turquoise are cleaner than straight up burning fossil fuels but still rely on fossil fuels:

In theory, pink hydrogen could be very, very cheap because the higher the temperature (waste coming off the core), the easier it is to split the atoms with electrolysis. I'm hoping if nuclear energy takes off again, we could see gen 4 or 5 reactors with pink hydrogen as primary purpose.

The main hurdle is the storage of hydrogen in an affordable, safe medium. The tanks in that boat are very large and very expensive.

+1 for nuclear power. I think people underestimate the power and sustainability of modern nuclear power and overestimate the risks associated with early nuclear reactors like the Soviet RBMK design. The main issue with nuclear power is the high capital costs to get going, so you end up spending a ton of money and time before you even start seeing a return, forget breaking even. With that said though, I still think that nuclear power is the future. While capital costs are high, fuel costs are incredibly low in comparison to other fueled power stations and can see far larger returns in the long term.

Hydrogen production would be a nice side-effect from a modern nuclear plant. Waste heat as you mentioned helps make the electrolysis process more efficient and excess power generation can be used to do the electrolysis itself. A big issue is that nobody seems to want a nuclear power station in their backyard because of the stigma of prior events like Chernobyl and Fukushima. Yes, modern reactors can't fail like these did, but it's hard to change minds.

The efficiency difference between solar/wind electrical generation to miles in a BEV vs a FCV is staggering. Even with off peak green energy (when most home charging is done) hydrogen fails to be cost effective for transportation.

And BEVs are selling like mad. They are a better solution with a lot of FUD from legacy industries.

No, BEVs are not selling as mad. As a matter of fact, trend is slowing down for BEVs! But you see that from your graph, if you know how to analyze it?!

BEVs are a fad, and continue to be as long as
1. Home charging isn't a feasible option for everyone,
2. Range is less than the petrol/diesel equivalent,
3. Charging times and infrastructure make road trips impossible,
4. The weight of the battery prevents it from being used in small runabouts,
5. Batteries require costly replacement every X years, and most importantly...
6. They cost an arm and leg with some insane year-per-year depreciation in value.

Exactly which is why I waited until 2017 to buy one. Same time my neighbor bought his AMG S65. AMG was a bit more money, quieter, slower and more plush. He averages 15 MPG, I charge at home mostly with two cross country trips averaging $25 a charge. Never a problem finding a charger and the car even tells me what chargers are busy, unlike his gas station roulette. Yes, It takes me 30 - 45 minutes to charge, but no time lost since we charge where we do other things, unlike his 10 minute loss every fill up. Battery replacement is looking like $8K at 250K miles in a few years, much cheaper than his ICE. Depreciation is also much greater on his AMG. The most telling thing is he has very low mileage on his AMG and drives his Prius to work while I have two around the country trips and 160K miles on mine. I won't go into his horrendous maintenance costs compared to my one headlight under warranty.

BEVs are the future, just a matter of education. Granted, not for all applications, just 90%.

Fad? Tell that to the guy that owns Tesla. Like him or loathe him, his inexplicable wealth is tied to his EV company.

Regardless, this thread is about hydrogen. Stay on topic please.

So how does FCV fulfill/eliminate the above issues?
1. I agree Biggest issue of BEV adoption for "Everyone" as not everyone has easy access to at home/overnight charging. Have a colleague who has been sent a sternly worded letter from his council for trying to charge his hybrid when using a protective cable cover and he obviously wasnt even leaving it in overnight. Asked for a solution/suggestion from the council and complete Radio silence ¬_¬ Good Luck Starmer with the 2030 target working out!!!
2. Sure but how many people are doing 300 miles in a single journey, and of these even how many are going to do that in one stint and not stop off during the trip where the could top up.
3. See my point above. Fast charging on modern BEVs means as long as you can get into a decent charger, by the time you have gone into a services, gone to the loo, had a snack/drink/stretch your legs you have already gotten back ~33% of your range? Sit around for another 10- 15 minutes and you are well on your way to recovering 50%
4. What do you determine as a small run about? Nissan Leaf is a fairly decent offering in that sort of category and has more than enough range for most people.
5. I think this falls under the same issues with engines in cars. If they do go wrong.....whooo boi, but there seems to be more and more understanding coming out about repairing/refreshing battery packs with issues.
6. TBH thats all cars not just BEVs that are becoming insanely expensive. Just built a F150 Platinum and an equivalent Lightning model and they are basically the same price but the BEV comes with $7k worth of incentives that actually makes the EV version cheaper......Good Lord..........

FCVs will "solve" Point 1, Points 2,3,4,5 and 6 are still going to be issues with FCVs

2. Toyota Mirai (FCV) has ~400 mile range to a tank, so barely more than an "equivalent" BEV and considerably shorter than a ICE powered vehicle "A full tank of hydrogen for the Hyundai Nexo can cost up to £100. The Nexo consumes 0.95 kilograms of hydrogen per 100 kilometers, so a 62-mile journey costs around £11.40"
3. We have all gone on about storage and generation of sufficent quantities of Hydrogen being the real roadblock for adoption
4. Weight isnt the issue but the volume of the tank/tanks is quite intruisive so it works in larger cars, especially where you can utilise a large center console to store one of the tanks but small cars ala Honda Jazz, Nissan Leaf etc are going to be really limited in range.
5. The actual Fuel Cell has degredation aspects to consider, whats the cost to replace one of them I wonder. I cant imagine it will be cheap
6. Thats just all new cars in general currently.

It's easy to get rich off a fad. Just look at the AI boom, crypto, or any of the fad diets... Or even Coca-Cola. I don't get how that sugary window cleaner with 0% natural flavour got popular.
